For a wide range of MRI and MRS applications
dual-tuned MR coils are used capable of multi-nuclear studies. Conventional
ultra-high-field preclinical dual-tuned coils are either surface loops having high
SNR over a limited FOV or volumetric coils with ultimate coverage compromised
by low SNR while used in Tx and Rx regimes. In this contribution we propose an
alternative design of the dual-tuned 1H/31P coil based on an open self-resonant
periodic structure, which doesn’t require variable lumped capacitors for tuning
and matching. It has been shown that the proposed coil is suitable for
studying energetics in human forearm muscles at 4.7T.
